摘要

The revegetation of disturbed, arid lands is one of the great challenges of a desert. It is not an impossible task, however, if one utilizes and properly manages both the natural and the man-made resources available. Through better understanding of the processes governing revegetation and the ability to control them, it is possible for man to more rapidly restore disturbed desert lands. Terrain manipulation to form moisture catchment basins, selection of seed from pioneering shrub species, preservation of existing shrub clump fertile islands in the soil, supplemental fertilization and irrigation, and transplanting vigorous shrub species are some of the important things that can be done to help restore disturbed desert land. Some of the costs can be off-set by restoring the land to economically important trees and shrubs, or grasses, instead of back to the original vegetation. Thousands of years of historical evidence of man's survival on arid lands attest to success in meeting the challenge of the desert. (41 references). (ERA citation 03:001379)
